FOOT SUPPORT Claude H. Daniels, Greenwich, Conn.

Application May 27, 1938, Serial N0. 210,399

3 Claims.

This invention relates to improvements in foot supports or cushion pads for shoes.

In my application, Ser. No. 128,649, iiled March 2, 1937, for Rubber product and method of mak- 5 ing same, I have disclosed a rubber-cork composivid e an improved form of foot support in which' a thin sheet of the deformable rubber-cork compound is used cut to fit the shoe and skived or otherwise reduced in thickness at certain portions thereof to provide a better fit by allowing the foot to drop at the weight bearing areas.

Fig. 1 is a perspective view of a shoe having the cushion pad therein;

Fig. 2 is a bottom view of the cushion pad;

Fig. 3 is a section taken on the plane indicated 3 3 in Fig. 2; and,

Fig. 4 is a section taken on the plane indicated 4 4 in Fig. 2.

My foot support may be shaped to fit any type of shoe such as l0 in Fig. 1, in which the foot support l 2 is placed in position over the heel seat and shank portion of the insole. The foot support comprises a layer of the rubber-cork compound M and a suitable cover I6.

The rubber-cork compound may be prepared as disclosed in my application Ser. No. 128,649,

led March 2, 1937in the form of thin sheets from which the pieces to form the foot support may be cut. This product is of a cellular nature but diifers from ordinary sponge rubber in that an impression received under pressure will remain after removal of the pressure. On the other hand, the product is generally shape-retaining and is not a soft, flowable or moldable mass which must be retained in an envelope. The product in the form of a foot support will not spread under pressure of a foot, but will be compressed and compacted under the weight of kthe body.

It is found to be desirable to have a foot sup-l port or a. foot cushion which will take up the least possible space when inserted in a shoe, and will add as little weight as possible to the shoe. The layer of rubber-cork compound is therefore cut from relatively thin sheets, for example, one- It is desirable to reduce the forward edge *ofv the pad to a thin edge which may be `carried out by skiving the edge as indicated at I8. The inside edgex which includes a portion 2U shaped to lap over the upper of the shoe may also be skived as at 22.

The thickness and weight of the foot support may be further reduced Without sacrificing the advantages of my foot support by skiving or grinding out the compound at those portions of the pad which bear the major portion of the Weight of the body. Fig. 2 shows the bottom of the pad in which the heel portion has a hollow 24- y ground therein to accommodate the heel of the foot. The outer edge of the pad is also reduced by skiving or grinding out the area 26 to allow the cuboid side of the foot to drop.

The pad I4 is or may be cemented in place over the insole of the shoe. adhesively secured to the outer face of the pad. In a preferred method of manufacture the cover` ing material or lining is adhesively secured to the The cover I6 may bey large sheets of the rubber-cork compound so that Y the foot supports may be cut out as unitsandv finished by skiving and grinding.

I claim:

1. A pad adapted to be inserted in a bootv or shoe comprising a thin sheet of deformable rubber-cork compound having a at top side shaped to t Athe heel and shank portions of the shoe, a cover cemented to the nat top side, the underside of the pad having a hollowed out heel seat and skived portions on the side edges and forward portion on the outer side edge thereof, the skived of the instep being substantially greater in area than that on the inner side thereof.

2. A pad adapted to be inserted in a boot or shoe comprising a thin sheet of deformable rubber-cork compound having avlat top side and shaped to fit the heel andshank portionsv only of the shoe, said pad having portions of reduced thickness in the region of the principal weightbearing areas, said pad having a thin skived edge at its forward end and a thin covering of flexible 'material cementedto the flat top side ofsaid pad.

3. A pad adapted to be inserted in a boot or shoe comprising` a thin sheet of rubber-cork compound having a at top side shaped to lit the heel and shank portions only of the shoe, the underside of the pad having a hollowed out heel seat and skived portions on the side edges and forward edge thereof, the skived portion on the outer side of the instep being greater than that,

on the inner side thereof.
